WEDGE FOR USE IN VIOOD RGLIJS AND THE LIKE.

Application fiIed April 5,

To all 207mm.- it may concern.

Be it known that I, CARL C. Her-airs, a citizen of the United States, residing at Grange, in the county of Franklin and State of Massachusetts, has invented new and useful lVedges for Use in -.Vood Rolls and the like, of which the following is a specification.

This invention relates to a wedge capable of general use, but particularly adapted for driving into the end of a heavy wood roll for use on textile and other machinery. The principal objects of the invention are to provide a wedge for use in place of, or in conjunction with, the ordinary flat wedges commonly used in the ends of such rolls, which will provide a more powerful spread ing effect on the wood than has been the case heretofore and thus bind or grip the rolls more firmly to the gudgeon which is .usually mounted on the shaft; also to provide for more firmly binding or gripping the circumferential ring which is frequently used; and in general to more securely anchor the shaft and gudgeon in the roller and thus secure longer service; also to effectively prevent the wedges from coming out and to provide positive means for preventing the ring from coming off. The invention also involves the positive clamping of the cover plates which are sometimes used to close up the ends of the Wooden rolls to prevent water or other liquids from reaching the gudgeon and rings and rusting them and decaying the wood.

Reference is to be had to the accompany ing drawing, in which Fig. 1 is an end view of a heavy wood roll adapted to be used on textile machinery and the like and designed for hard usage, the cover plate being broken away in part to show the construction behind it;

Fig. 9. is a central sectional view of the same;

F ig. 3 consists of two views, a side view and an end view of the improved wedge; and

Fig. 4 consists of two views, an end view and side View of the spreading tool adapted to be used'in connection with it.

The invention is shown as applied to a 0 wooden roll 10 which is large and heavy and is used in the presence of water and moisture. It has been the practice heretofore to provide a larger number than shown in these drawings of flat metal wedges ll driven into 1922. Serial No. 543,955

the end of the wooden roll with the grain to spread the wood to cause it to bear tightly against the gudgeon 12 which is driven into previously prepared openings in the end of the roll and which serves to center and secure the roll to the shaft 13 on which it is carried. These wedges also serve when driven in the proper place to spread the wood at the end against an iron ring 14 which surrounds the gudgeon and is driven into circular opening in the roll to help hold the gudgcon in place.

It has been customary heretofore to secure all this binding effect by means of flat metal wedges driven in at different angles so as tosecure the greatest effect. These wedges have been of wedge-shape and, of course, there was nothing to hold them in except friction. in orther words, they were no v positive. Furthermore, the spreading effect secured by them was not very great unless the end oi. the roll were practically. filled up with them.

I do not necessarily dispense with all these wedges but in many cases none of them need be used. I bore undersized holes into the wood between the arms of the gudgeon. these holes being slightly conical, if desired, and into them I drive cupshaped wedges 15 each formed by ordinary pressed metal processes from a round blank of sheet metal and each preferably having a flat flange 16. They are formed slightly conical and being driven into the. undersized holes they are held in position and spread the wood by the action of driving them in. After they are driven in a spreading tool, shown in Fig. 4:, is inserted. This in the form shown consists of two jaws 20 entirely separate from each other but having a central passage, 21 half of which located in. each one and also having a projection The two parts are put together and inserted in each of the wedges, one after the other, and then a rod 23 having a conical end 24: is driven in. This spreads the two halves of the spreading tooland forces the projections out at the side to force the metal of the cup 15 into the wood at the two opposite points. Then the tool 23 is with drawn and the two halves 20 can then be taken out easily.

Another way of providing a projection on the outer surface of the conical cup which is formed either of steel or brass, to intro- 1 other function.

in g

duce a rolling or heading tool Which is rotated to emboss a circular projection 17 on the cup. This serves the same purpose as the production of the projections above mentioned. v

The flat flanges 16 on the cup can be so arranged as to project over the edge of the ring 14 and positively hold it in position. I have also shown them as performing a11- A thin circular metal cover plate 18 is shown surroimding the shaft and projecting over the gudgeon and ring 14 and having its edge driven into the wooden roll. This is perforated at the center to receive the shaft and made water proof at that point by a packing 19. It is also provided with perforations for receiving the cups 15 and they are driven into the wood through it in the manner above described. In this way, they serve to hold this cover plate firmly in position. These cover plates are used to prevent water or other liquids from reaching the gudgeon and rings fitted into the ends of the rolls and they help inaterially to prevent the decay and rotting of the parts of the wood which must be in good condition to hold the gudgeon and shaft firmly.

Of course the most important advantage of this invention lies in the fact that a more powerful wedging or spreading effect on the wood is secured and also the wedges are held positively on account of being forced out to form the head 17 or projection above described. This causes a much firmer 'grip on the sides of the gudgeon 12 and therefore more thoroughly anchors the shaft to the wood roll and insures a longer service thereof Furthermore, it positively holds in the ring 14 and the cover plate 18 as above described. It can be used for any one of the three mentioned purposes without employing it for the other by locating it differently or if the cover plate 18 is not used then the flange 16 of each. wedge preferably engages directly on the edge of the ring 14. 7

Although I have shown and described only two forms of the invention, I am aware of the fact that other modifications can be made therein by any other person skilled in the art without departing from the scope of the invention as expressed in the claims.
